gullibell, my experience is more or less the same. In my squadron there was an A-4 sheet with instructions explaining the basic functions and little more. Some pilots never used tilt control, for instance.
And reading some civilian transport accident reports, in commercial airlines is the same. Pilots do not master the use of weather radar because there is not an specific training course about it.
To add something to the debate, I think that the primary source for VFR navigation when you are not familiar with the area in which the flight is conducted, should be a VFR CHART. I mean, a paper chart or a digital moving map. Radar and EGPWS are important tools for navigation, but a good map in a correct scale is paramount.
